Using a liner is best, but it's not absolutely necessary. I'll bet you're using solderable wire, aren't you? If you have some magnet wire with a tougher coating (such as Formvar or Belden® heavy-armored Polythermaleze®) it's not so likely to be damaged. You'll have to remove the coating at each end, because a soldering iron won't melt it. 73, Mike www.w0btu.com _________________ Topband Reflector Archives - http://www.contesting.com/_topband
